Comment:

 Replying to [comment:1 hamish]:

 > perhaps for r.ros because output= is just a prefix for a number of
 output maps?

 See #2136 for the prefix/basename discussion and fix of overwrite for
 G7:i.pca and G7:r.texture (r58311).

 However, from the quick test, this seems to work in the current trunk
 (r59190):

 {{{
 $ r.ros model=aaa moisture_1h=bbb moisture_live=ccc output=ddd
 r.ros complete. Raster maps <ddd.base>, <ddd.max> and <ddd.maxdir>
 created.

 $ r.ros model=aaa moisture_1h=bbb moisture_live=ccc output=ddd
 ERROR: Raster map <ddd.base> already exists in mapset <PERMANENT>

 $ r.ros --overwrite model=aaa moisture_1h=bbb moisture_live=ccc output=ddd
 r.ros complete. Raster maps <ddd.base>, <ddd.max> and <ddd.maxdir>
 created.
 }}}

 The problem now is that when I already have map named as the
 prefix/basename, it will not let me proceed:

 {{{
 $ r.mapcalc "eee = 1"
 $ r.ros --overwrite model=aaa moisture_1h=bbb moisture_live=ccc output=eee
 ERROR: option <output>: <eee> exists.
 }}}

 This may be good for safety but then the error message (or the situation)
 is confusing because when I do overwrite, it will not overwrite that
 `eee`, it will create new ones (`eee.*`) and I will still have the old
 `eee`.
